Connection Caching for WWW Servers and Proxies

Overview

This paper proposes connection caching to reduce the overhead of accessing WWW pages. Connection caching means that a WWW server or a WWW proxy server does not release its connection with a client or a peer but retains it and uses it again after the transmission is completed. The retained connection is cached and it is used for future access. Connection caching reduces network traffic and server load. This paper shows that the hit rate of connection caching for WWW accesses is high and connection caching is effective. This evaluation is based on actual logs from a server and a proxy server. The logs are records of 350 days. The log from the proxy server includes more than 14 million accesses.
